WARNINGS & SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS - THIS MANUAL CONTAINS IMPORTANT SAFETY
INSTRUCTIONS FOR THE
TOW-PRO®ELITE
BRAKE CONTROLLER.
DO NOT OPERATE THE CONTROLLER UNLESS YOU HAVE READ AND UNDERSTOOD
THIS MANUAL AND THE CONTROLLER IS INSTALLED AS PER THESE INSTALLATION
INSTRUCTIONS.
ENSURE THAT YOUR TRAILER BRAKES ARE INSTALLED AND ARE OPERATING CORRECTLY:
IMPROPERLY INSTALLED AND/OR FAULTY TRAILER BRAKES CAN CAUSE ERRATIC
VEHICLE OR TRAILER BEHAVIOUR WITH THE POTENTIAL TO CAUSE A ROAD ACCIDENT.
FOR THIS REASON, IT IS OF UTMOST IMPORTANCE THAT YOUR TRAILER BRAKING
SYSTEM BE INSTALLED/MAINTAINED BY A QUALIFIED INSTALLER.
ALWAYS CHECK BRAKES AT LOW SPEED EACH TIME A TRAILER IS ATTACHED TO YOUR
VEHICLE.
1. Ensure that the Tow-Pro®Elite is mounted securely in a fixed location. Failure to mount securely
will result in inaccurate braking force measurements and incorrect braking of the trailer.
2. Ensure that the Tow-Pro®Elite is installed inside the vehicle cabin and away from any
environmental conditions that may cause damage, including engine heat, submersion in water,
salt spray and humidity. Exposure to these conditions may cause damage to the unit’s circuitry
and may cause erratic trailer braking.
3. A Fuse or Circuit Breaker of appropriate rating must be installed to protect the vehicle system.
Please refer to the installation instructions starting on Page 7 for specific instructions on where
to install the Fuse or Circuit Breaker and for appropriate Fuse or Circuit Breaker rating. The Fuse
or Circuit Breaker must be installed as close as possible to the battery.
TOW-PRO® ELITE (EBRH-ACCV3-NA) TRAILER BRAKE CONTROLLER
The Tow-Pro®Elite is an electric trailer brake controller designed to suit most common
trailer braking applications whilst requiring minimal dash space and being simple to
install and operate.
The Tow-Pro®Elite offers selectable Proportional or User Controlled trailer braking
modes allowing the user to choose the braking style depending on the road or terrain
conditions, vehicle type, or driver preference.
The Tow-Pro®Elite features Active Calibration which constantly monitors the direction
of travel and will even calibrate with no trailer attached whilst maintaining the ability to
mount in any orientation.
The unit is able to operate electric trailer brakes from either 12V or 24V vehicle
systems without the need for manual selection or extra components/ wiring.
The unit is able to operate Electric / Hydraulic trailer brakes from 12V vehicle systems.

WARNINGS & SAFETY INSTRUCTIONS
4. Ensure the remote head push-button activates correctly when installed into surfaces with a
thickness greater than 9/64” (3.6mm). Failure to activate correctly would result in not being able
to activate the override function or change modes.
5. Ensure that the wire(s) and all connections used to install the Tow-Pro®Elite are suitably rated to
supply the required current to simultaneously operate the trailer electric brakes and stop lamps.
Incorrect wiring can result in reduced (or total loss of) trailer braking and/or damage to property
or persons.
6. The Tow-Pro®Elite is suitable for trailers with electric brakes up to three axles. Note that Federal
and State laws apply to trailer weights and brake controller requirements. Please consult your
local authority to ensure you comply with the legal requirements.
7. Do not drive with the Tow-Pro®Elite while a fault code is active. Fault codes of the Tow-Pro®
Elite may indicate conditions that make it unsafe or illegal to drive, including unreliable trailer
brakes or failure of brake lights.
8. During the calibration step of the Tow-Pro®Elite, braking of the trailer may be inconsistent.
REDARC recommends calibrating the Tow-Pro®Elite without a trailer attached.A normal drive of
a few miles will do for this purpose. If calibrating with a trailer attached, then the recommended
dial setting for the Tow-Pro®Elite is 4 or less.
1. Ensure that a correct grounding point is used. Vehicles often have ungrounded metal
reinforcements under the dash and these points are not suitable grounds. Bad grounding of the
unit will result in poor or no operation.
2. The Tow-Pro®Elite does not act as a trailer lights voltage converter. If the trailer brake lights
operate on a different voltage, damage to the vehicle; trailer and/or Tow-Pro®Elite and
associated wiring may result. This may also result in reduced (or total loss of) trailer braking.
3. When installing the Tow-Pro®Elite Remote Control to a thin panel, washers are recommended
to reinforce the structure of the panel.
4. Do NOT exceed Tow Vehicle and Trailer weights and specifications. Failure to abide by the towing
regulations, including maximum loads, may result in a fine, or in case of an accident, refusal of
the insurance claim, and the possibility of further legal action.
If the tow vehicle or trailer’s maximum load is exceeded, police and transport authorities have
the power to order the combination off the road until the issue is corrected. This may necessitate
leaving the trailer on the side of the road while a vehicle with suitable towing capacity is sourced
or the trailer load is reduced. Please contact your local authorities for further information.
5. If no trailer is connected, Active Calibration may occur as normal without any indication from the
LED. The LED will already be Blue when the trailer is connected. Essentially, whether a trailer is
connected or not, just drive normally and Active Calibration will ensure the Tow-Pro®Elite learns
the correct direction of travel.

2 INSTALLATION
2.1 Mounting the main unit
The Tow-Pro®Elite should be mounted inside the vehicle cabin using either 5/32”
(M4) diameter screws or other secure fitting methods at the mounting points
provided. It is essential to mount the unit in a location which allows access to the
intended remote head location.
The Tow-Pro®Elite can be mounted in any orientation as long as the installation
is secure and the main unit cannot move or change orientation once installed. A
change of orientation will affect the system calibration.
Ensure that the Tow-Pro®Elite is mounted securely in a fixed location. Failure
to mount securely will result in inaccurate braking force measurements and
incorrect braking of the trailer.
Ensure that the Tow-Pro®Elite is installed inside the vehicle cabin and away
from any environmental conditions that may cause damage, including engine
heat, submersion in water, salt spray and humidity. Exposure to these conditions
may cause damage to the unit’s circuitry and may cause erratic trailer braking.
Any Secure Orientation OK
Do Not Mount to Cables / Wiring Looms
(Must be mounted to a rigid or solid object or surface)

2 INSTALLATION
2.2 Wiring the brake controller
REDARC Electronics manufactures a number of vehicle-specific wiring
harnesses for quick and easy installation (refer to REDARC’s website for details).
The universal wiring harness included with th EBRH-ACCV3-NA kit is the TPH-
025 ‘Universal Harness’ which is typically used for older vehicles not covered by
our range of wiring harnesses. Please follow the subsequent instructions for all
custom installations.
A Fuse or Circuit Breaker of appropriate rating must be installed to protect the
vehicle system. Please refer to the installation instructions starting on Page 7
for specific instructions on where to install the Fuse or Circuit Breaker and for
appropriate Fuse or Circuit Breaker rating. The Fuse or Circuit Breaker must be
installed as close as possible to the battery.
Ensure that the wire(s) and all connections used to install the Tow-Pro®Elite
are suitably rated to supply the required current to simultaneously operate the
trailer electric brakes and stop lamps. Incorrect wiring can result in reduced (or
total loss of) trailer braking and/or damage to property or persons.
The Tow-Pro®Elite does not act as a trailer lights voltage converter. If the trailer
brake lights operate on a different voltage, damage to the vehicle; trailer and/
or Tow-Pro®Elite and associated wiring may result. This may also result in
reduced (or total loss of) trailer braking.

2 INSTALLATION
2.2.1 Red Wire (Vehicle Brake light) Connection
The requirements for a suitable connection of a brake controller trigger wire are
quite specific. This connection point must:
• Provide a voltage of the same voltage level as the “Start Battery*” while the
vehicle brakes are applied.
• Have 0 volts output while the vehicle brakes are not applied
• Accept battery voltage input when the brake controller manual over-ride is
operated and illuminate at least the trailer brake lights.
• Accept the battery voltage input as above without causing any damage, spurious
vehicle operation or erroneous fault indication.
A relay should not be installed to drive the red wire as this would prevent the override
feature from working and may introduce dangerous voltage spikes.
* Start Battery voltage output means, directly from the Start Battery and within 0.4V of Supply (Black
wire) voltage.
